The answer is 3√5. You use the distance formula: √((x2-x1)^2+(y2-y1)^2)
The answer is c I might be wrong
∠QRS and ∠CDE are congruent.
∠RST and ∠DEB are congruent.
∠STQ and ∠EBC are congruent.
∠TQR and ∠BCD are congruent.
You can conclude the above angles are congruent because ∠R and ∠D has the same sign on their angle and so does ∠S and ∠E.
The answer is 2 because you multiply them both
